Welcome All People!
I am brendasue of Kates Cabin Bird Sanctuary in Texas. I invite you to come in for a Break where Human Nature Meets Mother Earth Nature and Father Space Nature!! I share my digital images from the Private Bird Sanctuary. In addition we have Field Trips and visit places on the computer in a Fantastic World Tour. It is my intention to inspire You to think about all Life on Earth for the Future of Humanity. It is my Hope that You will discover New Joy!

Hi Everybody!!

Welcome to my Hometown!!

The Golden Light and the Golden Little King (Golden Photo Blog)

Sunset

The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon in the west. The ray path of light from the setting Sun is highly distorted near the horizon because of atmospheric refraction, making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk, which is the moment at which darkness falls, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight.

Colors

Ash from volcanic eruptions, trapped within the troposphere, tends to mute sunset and sunrise colors, while volcanic ejecta that is instead lofted into the stratosphere (as thin clouds of tiny sulfuric acid droplets), can yield beautiful post-sunset colors calledafterglows and pre-sunrise glows. A number of eruptions, including those of Mount Pinatubo in 1991 and Krakatoa in 1883, have produced sufficiently high stratospheric sulfuric acid clouds to yield remarkable sunset afterglows (and pre-sunrise glows) around the world. The high altitude clouds serve to reflect strongly-reddened sunlight still striking the stratosphere after sunset, down to the surface.Sunset colors are typically more brilliant than sunrise colors, because the evening air contains more particles than morning air.[4][5][7][10]As a ray of white sunlight travels through the atmosphere to an observer, some of the colors are scattered out of the beam by air molecules and airborne particles, changing the final color of the beam the viewer sees. Because the shorter wavelength components, such as blue and green, scatter more strongly, these colors are preferentially removed from the beam.[4] At sunrise and sunset, when the path through the atmosphere is longer, the blue and green components are removed almost completely leaving the longer wavelength orange and red hues we see at those times. The remaining reddened sunlight can then be scattered by cloud droplets and other relatively large particles to light up the horizon red and orange.[5] The removal of the shorter wavelengths of light is due to Rayleigh scattering by air molecules and particles much smaller than the wavelength of visible light (less than 50 nm in diameter).[6][7] The scattering by cloud droplets and other particles with diameters comparable to or larger than the sunlight's wavelengths (> 600 nm) is due to Mie scattering and is not strongly wavelength-dependent. Mie scattering is responsible for the light scattered by clouds, and also for the daytime halo of white light around the sun (forward scattering of white light). Without Mie scattering at sunset and sunrise, the sky along the horizon has only a dull-reddish appearance, while the rest of the sky remains mostly blue and sometimes green.[8][9][10]

Sometimes just before sunrise or after sunset a green flash can be seen.

Golden hour (photography)

From Wikipedia, the free encyclopedia

In photography, the golden hour (sometimes known as magic hour, especially incinematography) is the first and last hour of sunlight during the day,[1] when a specific photographic effect is achieved due to the quality of the light.

Overview

Typically, lighting is softer (more diffuse) and warmer in hue, and shadows are longer. When the sun is near the horizon, sunlight travels through more of the atmosphere, reducing the intensity of the direct light, so that more of the illumination comes fromindirect light from the sky (Thomas 1973, 9–13), reducing the lighting ratio. More blue light is scattered, so that light from the sun appears more reddish. In addition, the sun's small angle with the horizon produces longer shadows.

“Hour” is used here quite loosely. The character of the lighting is determined by the sun'saltitude, and the time for the sun to move from the horizon to a specified altitude depends on a location's latitude and the time of year[2] (Bermingham 2003, 214). In Los Angeles, California, at an hour after sunrise or an hour before sunset, the sun has an altitude of about 10°–12°.[3] For a location closer to the equator, the altitude is greater (or the time less), and for a location farther from the equator, the altitude is less (or the time greater). For a location sufficiently far from the equator, the sun may not reach an altitude of 10°, and the golden hour lasts for the entire day in certain seasons.

In the middle of the day, the bright overhead sun can create too-bright highlights and darkshadows. The degree to which overexposure can occur varies because different types of film and digital cameras have different dynamic ranges. This harsh-lighting problem is particularly important in portrait photography, where a fill flash is often necessary to balance lighting across the subject's face or body, filling in strong shadows that are usually considered undesirable.

Because the contrast is less during the golden hour, shadows are less dark, and highlights are less likely to be overexposed. Inlandscape photography, the warm color of the low sun is often considered desirable to enhance the colours of the scene.

WELCOME Everybody!!

I invite You to come visit this Blog anytime you want to!! Please leave notes or comments and please share! I want to reach all people, but especially those who are in Hospitals, Retirement Homes, or Schools. I want to bring life inside to All who cannot go out. We are all Nature Lovers here in this Blog Community, from all Countries on Earth. If you know someone lost or lonely, help them get connected. Friends await You!

I want to meet Gardeners, Artists, Nature Lovers and see the World through others photos and stories. I share the adventures of mine at Kates Cabin Bird Sanctuary in Texas on Google+ in digital compositions of my Nature Photos.
